Volatile organic compounds (VOCs) are primarily monitored using canisters in accordance with US EPA Method TO-15. However, analysis of these ‘air toxics’ is challenged by the ever-greater range of analytes and concentrations of interest, and by the range of temperatures and humidities at sampling locations.

Featuring an innovative water management mechanism which preserves your GC–MS, Markes International instrumentation overcomes these difficulties to deliver unbeatable analytical performance for canister air samples.

The system described operates cryogen-free, and allows confident GC–MS canister analysis of both regular (ppbv) and trace-level (pptv) polar and non-polar VOCs in humid environments, in compliance with US EPA Method TO-15 and Chinese EPA method HJ 759 .

By viewing this on-demand presentation you will learn:

• How you can monitor ‘air toxics’ – including very volatile compounds and polar species – in humid canister air.
• How you can achieve excellent system performance for trace-level TO-15 samples even at 100% relative humidity.
• How this water-management technology can be extended to on-line monitoring.
